The rivet shaft is more compressed in its edge regions that are aligned with the bulges in the rivet hole. <??>AN Independent claim is also included for the following: a method of making an electrical contact between a contact rivet and a bearer element and a piston for use in the inventive method.

Description

In Relais wird ein elektrischer Schaltkontakt häufig über eine mit einem Kontaktstück versehene Metallfeder realisiert. Die Kontaktfeder wird mechanisch oder elektrisch über eine Betätigungseinrichtung mit hoher Schaltfrequenz zwischen offener und geschlossener Stellung hin und her bewegt.In relays, an electrical switch contact is often used with a metal spring provided a contact piece realized. The contact spring is mechanically or electrically via an actuator with high Switching frequency between open and closed position back and forth emotional.

Das Kontaktstück besteht meist in einem balligen oder kronenförmigen Niet, der im äußeren Bereich der Kontaktfeder angenietet ist und besonders gut leitfähig ist.The contact piece usually consists of a spherical or crown-shaped Rivet riveted to the outer area of the contact spring and special is well conductive.

Zur Herstellung der Nietverbindung wird in die Kontaktfeder ein Loch gestanzt und der pilzförmige Kontaktniet hineingesteckt. Anschließend wird das durchgesteckte Ende des Nietschafts mit einem Nietstempel gestaucht, so daß eine formschlüssige Verbindung zwischen Niet und Kontaktfeder entsteht. Im Stand der Technik werden runde Nietlöcher und Stempel mit im wesentlichen flachem bzw. linsenkopfförmigem Ende verwendet.To make the rivet connection, a hole is made in the contact spring punched and the mushroom-shaped contact rivet inserted. Then will the inserted end of the rivet shaft is compressed with a rivet punch, so that a positive connection between the rivet and contact spring arises. In the prior art, round rivet holes and stamps are used used essentially flat or lenticular end.

Aus JP-A-01241722 ist ein Kontaktelement mit den im ersten Teil des Anspruch 1 angegebenen Merkmalen bekannt. Dort weist das in einer Kontaktfeder vorgesehene Loch nach innen vorspringende Zacken auf, die sich beim Nietvorgang in den zylindrischen Nietschaft eindrücken.From JP-A-01241722 is a contact element with the in the first part of the Claim 1 specified features known. There that points in a contact spring provided hole protruding inwards on itself press into the cylindrical rivet shaft during the riveting process.

Mit der fortschreitenden Miniaturisierung in der Relaistechnik sollen alle Bauteile eines Relais, darunter insbesondere die Kontaktfeder, möglichst klein und schmal gehalten werden. Dadurch wird der Abstand des Nietlochs zu den Seitenkanten der länglichen Kontaktfeder so klein, daß durch den Nietvorgang Materialverwerfungen in der Kontaktfeder auftreten können. Dies führt zu erhöhter Bruchgefahr, die es gerade für Sicherheitsrelais zu vermeiden gilt.With the advancing miniaturization in relay technology all components of a relay, including in particular the contact spring, if possible be kept small and narrow. This will distance the Rivet hole to the side edges of the elongated contact spring so small that Due to the riveting process, material distortions occur in the contact spring can. This leads to an increased risk of breakage, which is particularly important for safety relays to avoid.

Zusätzlich soll die Nietverbindung eine mechanische Belastbarkeit und geringen elektrischen Übergangswiderstand aufweisen. Dennoch entstehende Stromwärme soll möglichst gut in die Kontaktfeder abgeleitet werden; deshalb ist auch hohe thermische Leitfähigkeit der Nietverbindung erwünscht.In addition, the rivet connection should have a mechanical strength and have low electrical contact resistance. Still emerging Current heat should be dissipated as well as possible into the contact spring become; therefore there is also high thermal conductivity of the riveted joint he wishes.

Aufgabe der Erfindung ist es, Materialschädigungen der Kontaktfeder beim Nietvorgang zu minimieren und trotzdem gute mechanische, thermische und elektrische Verbindung zwischen Kontaktniet und Kontaktfeder zu gewährleisten.The object of the invention is to damage the contact spring material to minimize during the riveting process and still good mechanical, thermal and electrical connection between the contact rivet and the contact spring guarantee.

Die Lösung der Aufgabe gelingt mit dem in Anspruch 1 angegebenen Kontaktelement und dem in Anspruch 3 angegebenen Nietverfahren. Danach weist das Nietloch seitliche Ausbuchtungen auf, und der Nietschaft wird in seinen auf diese Ausbuchtungen ausgerichteten Randbereichen stärker gestaucht.The problem is solved with that specified in claim 1 Contact element and the riveting method specified in claim 3. After that the rivet hole has lateral bulges and the rivet shaft in its edge areas aligned with these bulges more compressed.

Bei dieser Gestaltung sind die beim Nietvorgang im Trägerelement (Kontaktfeder) auftretenden Kräfte im Bereich der Ausbuchtungen abgeschwächt. Die im teilweise stärkere Stauchung des Nietes gewährleistet wiederum die formschlüssige und gut leitende Verbindung zwischen Kontaktniet und Kontaktfeder.With this design, they are in the carrier element during the riveting process (Contact spring) forces occurring in the area of the bulges weakened. The partially stronger compression of the rivet is guaranteed again the positive and well-conductive connection between the contact rivet and contact spring.

In der Weiterbildung der Erfindung nach Anspruch 2 und 4 werden Materialverwerfungen in den schmalen Stegen zwischen dem Nietloch und den Seitenkanten der Kontaktfeder vermieden. Dabei wird der Niet in den an die Ausbuchtungen angrenzenden Randbereichen stärker als in seinem Innenbereich gestaucht und so eine gute Verbindung erzielt.In the development of the invention according to claims 2 and 4 Material warping in the narrow webs between the rivet hole and avoided the side edges of the contact spring. The rivet is in the border areas bordering the bulges stronger than in its Compressed inside and so a good connection is achieved.

Gemäß Anspruch 5 ist der Nietstempel so gestaltet, daß sein Stirnprofil in bestimmten Randbereichen weiter vorragt ist als in seiner Mitte. Dieser Längenunterschied soll dabei nicht größer sein als die gesamte, durch das Nietloch hervorstehende Länge des Nietschafts.According to claim 5, the rivet punch is designed so that its end profile protrudes further in certain edge areas than in the middle. This The difference in length should not be greater than the total, due to that Rivet hole protruding length of the rivet shaft.

Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand der Zeichnung näher erläutert. Darin zeigt, jeweils in schematischer Perspektivansicht:

Fig. 1
einen Teil einer Kontaktfeder und einen davon getrennten Kontaktniet;
Fig. 2
Kontaktfeder, Kontaktniet und Stempel unmittelbar vor dem Nietvorgang; und
Fig. 3
das fertige Kontaktelement.
An embodiment of the invention is explained below with reference to the drawing. It shows, each in a schematic perspective view:
Fig. 1
part of a contact spring and a separate contact rivet;
Fig. 2
Contact spring, contact rivet and stamp immediately before the riveting process; and
Fig. 3
the finished contact element.

In Fig. 1 ist das freie Ende einer Kontaktfeder 11 mit einem Betätigungselement 12 gezeigt, das sich zum Beispiel von einem mechanischen Betätiger führen läßt. In den Endbereich der schmalen Kontaktfeder 11 ist ein Nietloch 13 gestanzt, das zu den Seitenkanten der Kontaktfeder 11 hin zwei runde Ausbuchtungen 14 aufweist.In Fig. 1 the free end of a contact spring 11 is shown with an actuating element 12 which can be guided, for example, by a mechanical actuator. In the end portion of the narrow contact spring 11, a rivet hole 13 is punched, which has to the side edges of the contact spring 11 through two round bulges fourteenth

Die durch die beiden Ausbuchtungen 14 verlaufende Achse braucht nicht vollständig senkrecht zu den Seitenkanten der Kontaktfeder 11 zu stehen; in gewissen Fällen ist es vorteilhaft, sie leicht verdreht dazu auszurichten.The axis running through the two bulges 14 need not be completely perpendicular to the side edges of the contact spring 11 ; in certain cases it is advantageous to align them slightly twisted.

Unter der Kontaktfeder 11 ist ein herkömmlicher, pilzförmiger Kontaktniet 15 mit einer balligen Oberseite 16 und einem zylindrischen Nietschaft 17 an seiner Unterseite gezeigt.Under the contact spring 11 , a conventional mushroom-shaped contact rivet 15 is shown with a spherical top 16 and a cylindrical rivet shaft 17 on its underside.

Wie in Fig. 2 zu sehen, wird der Nietschaft 17 durch das Nietloch 13 bis zum Anschlag mit der Oberseite 16 des Kontaktniets 15 hindurchgesteckt. Anschließend werden Kontaktfeder 11 und Kontaktniet 15 in einem Nietvorgang mittels eines Stempels 18 verbunden. Dabei staucht der Stempel 18 das weichere Material des Nietschafts 17 so, daß eine formschlüssige Verbindung zwischen Niet 15 und Kontaktfeder 11 entsteht.As can be seen in FIG. 2, the rivet shaft 17 is pushed through the rivet hole 13 up to the stop with the upper side 16 of the contact rivet 15 . The contact spring 11 and the contact rivet 15 are then connected in a riveting process by means of a stamp 18 . The punch 18 compresses the softer material of the rivet shaft 17 so that a positive connection between the rivet 15 and contact spring 11 is formed.

Der Stempel 18 weist dabei kein flaches Stirnende auf, sondern ist torbogenartig ausgefräst, so daß er zwei längere Randbereiche 19 aufweist. Beim Nietvorgang werden daher zunächst nur die unter diesen Randbereichen 19 befindlichen Bereiche des Nietschafts 17 gestaucht und erst danach und entsprechend schwächer der Innenbereich.The stamp 18 has no flat end, but is milled out like an arch, so that it has two longer edge areas 19 . During the riveting process, therefore, only the areas of the rivet shank 17 located under these edge areas 19 are compressed, and only then and correspondingly weaker is the inner area.

Insgesamt ist der Querschnitt des Stempels 18 kreisförmig und größer als der des zylindrischen Nietschafts 17.Overall, the cross section of the punch 18 is circular and larger than that of the cylindrical rivet shaft 17 .

Fig. 3 zeigt das freie Ende eines fertigen Kontaktelements. Man erkennt die stärkere Stauchung des Nietschafts 17 in den Randbereichen 20, die die Ausbuchtungen 14 des Nietlochs 13 voll mit Material überdecken und dadurch eine formschlüssige Verbindung guter Leitfähigkeit ergeben.Fig. 3 shows the free end of a finished contact element. One can see the greater compression of the rivet shaft 17 in the edge regions 20 , which completely cover the bulges 14 of the rivet hole 13 with material and thereby result in a positive connection of good conductivity.

Die Verbesserung der mechanischen, thermischen und elektrischen Verbindungseigenschaften beruht vor allem auf dem durch die Ausbuchtungen 14 erreichten größeren Oberflächenkontakt zwischen Kontaktfeder 11 und Niet 15. Die spezielle Form des Stempels 18 bewirkt eine stärkere Stauchung des Nietschafts 17 in den entsprechenden Randbereichen und damit eine Materialanhäufung in den Ausbuchtungen 14. The improvement in the mechanical, thermal and electrical connection properties is based above all on the greater surface contact between the contact spring 11 and the rivet 15 achieved by the bulges 14 . The special shape of the plunger 18 causes the rivet shaft 17 to be more strongly compressed in the corresponding edge regions and thus a material accumulation in the bulges 14.

Das obige Ausführungsbeispiel bezieht sich auf die Befestigung eines Kontaktniets am freien Ende einer Kontaktfeder. Die Erfindung ist auch bei vergleichbaren Nietverbindungen, wie z.B. der Nietverbindung des unteren Endes der Kontaktfeder mit dem Anschlußstück etwa eines Relais, anwendbar.The above embodiment relates to the attachment of a Contact rivets on the free end of a contact spring. The invention is also at comparable rivet connections, e.g. the rivet connection of the lower one End of the contact spring with the connector such as a relay, applicable.

Ebenso sind alternative Ausgestaltungen des unrunden Nietlochs 13, z.B. mit drei oder mehr Ausbuchtungen 14 und dazu entsprechend geformte Nietstempel 18 denkbar.Alternative configurations of the non-circular rivet hole 13 are also conceivable, for example with three or more bulges 14 and correspondingly shaped rivet punches 18 .
